Two U.S. economists win Nobel for economics (KSAT)

Alvin E. Roth of Harvard University and Lloyd Shapley of UCLA have been
awarded the Nobel Prize in economics for their work in market design and
matching theory, the Royal Swedish Academy of Sciences announced Monday.

Roth and Shapley's work focuses on finding the most efficient way to match
parties in a transaction, whether it be students to schools or organ donors to
recipients, according to the academy.

Shapley used game theory to study matching models, and Roth built on them to
make real-world changes to existing markets, including school choice and organ
transplants, the academy said.

Elements of their work are built into software that guides kidney donations in
the United States, as well as in school choice models in New York, Boston, New
Orleans and other U.S. cities, Roth told reporters Monday.

Roth, who was awakened by an early morning call about their win, said he was
not expecting the prize but was honored to share it with Shapley.

"I'm sure when I go to the class this morning my students will pay more
attention," he said.

The economics prize is the sixth and final of the annual awards that spotlight
the world's top scholars ...
